My meatloaf is more of a sweet teriyaki flavor. I use about 1.5 pounds of hamburger (I will mix beef and venison if I have venison on hand), 1 egg, 1 cup oatmeal, 1/4 c ketchup, 1/4 cup Mr. Yoshida's original teriyaki sauce (soy sauce would work too), 1/4 cup brown sugar, 1 tsp liquid smoke, 2 tsp onion powder, 1 tsp garlic powder, 1 tsp black pepper, 1 tsp salt, 1/8 tsp red pepper flakes.
For the sauce - 1/3 c ketchup, 1/3 c Mr. Yoshida's sauce, and about 3 tbsp brown sugar. Mix together.
Mix together, then shape into loaf form on a broiler pan. Bake at 375 for about 1 hour. About 20 minutes before finished, add the sauce and finish cooking. Internal temperature should be 170.
